[CDO][0.8.0] Concurrency [message #106101]

I updating our prodcution system with the latest version of CDO.
(we are still using the version from october)

I'm going through all the changes we've made... and it is funny that we
found the same fixes at many places.

One of them.. we have almost the same change.

The problem with CDOViewImpl.getObject() its that we need to put
synchronization around lastLookup and when we assign the lastLookup

if (id.equals(lastLookupID))
{
<< CONTEXT COULD SWITCH HERE !!!
return lastLookupObject;
}

Let me know what you think.

Simon,

That's a good idea. I was too eager with sparing synced statements ;-(
